To all w/zon't it may concern; v

B it'known that I, CARL P. PAULY, a citizen of the United States, resident of Saul: Center, county of Stearns, 'State of 'Minnesota, haveinvented certain new and useful Improvements in Automatic Stock- Feeding Apparatus, of is a specification.

cally delivering a predetermined quantity of feed to the'fmanger'at a predetermined A further object is to provide an apparatus whichwill be positiveand rellable n its operation and comparatively s1mp-le 1n and maintain.

Other objects'of theinvention will ap-J perige -m the following detailed description."

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out inthe claims. i

In the accompanying drawings -form1ng part of this specification,

Figure 3 is a sectional view on the line 3-3 of Figure 1, looking in the direction of the arrow,

Figure 5 is a sectional 5-5 of Figure 1, looking in the direction Figure 6 is a detail view of the mecha-. nism actuated by the alarm post of the t1me piece for tripping the feed hopper release. In the drawing, 2 represents a suitable manger having the usual means 3 for tying stoclgsuch as cows, therein. 4 is a post at one side of the manger and 5 is a hopper extending along the tip-up above the manger and provided with a hinged bottom 6 which, when open, allows the contents of-the hopper to drop by gravity into" the manger beneath. Pins 7 are provided in which the following The object of my invention is'to provide .an-apparatus for use 1n connect on with view on the line NIT-D sTA'r s PATE 1 1 Specification of te mma e P tgflt p pq, 1922;; Application filed M y s, 192'1.

spring .2 orma11y tends tQwithdraw the lever 23v from engagement with the finger 21 and allow the lever 17 to drop and release 1 5 the hammer. A bracket 27 is; mounted near the loweri 'end of the;lever 23.anol carries,

a cam 28,'the edge ofwhich is incontact. 1:

witht-he lever 23 against the tension of the spring 26. A stud 29 is" inountedin thecam 2S and has a flat end portion 30which engages the fork 31 on the alarm post of the" time piece 32. l/Vhen this cam is in the p0 sition shown'in Figure 6, with its high side in contact with the lever, thepin on the lever will be held-in engagement with the finger 21 on the lever 17 but when the cam is revolved until its low side contacts with '7 the trip lever, thev spring 26 will swing the said. lever on its pivots sufficiently to re,-. lease the finger 21, allow the lever 17 to drop and release the hammer 15 which,

swingingfdown to theposition shown in" Figure 4, will strike the bar 12, trip the,

latches Sand release the hinged floor of the hopper, allowing the feed therein to drop by gravity into the manger beneath This movement may take place'at any time for which the clock is set. The operator'mayf theret'ore'fill the hopper with the desired 7 feed and leave the barn for a number of hours, knowing that when the clock reaches a certain predetermined point, the mechanism will be automatically tripped and the feed will be delivered to the stock without any attention whatever on the partiof the person in charge.

I am aware that automatic stock feeders have heretofore been devised but my invention or improvement consists in simplifying and making more positive and reliable the operation of the parts, as evidently a device of this kind must operate at the time desired or it would be wholly useless for the purpose designed. 1 I have accomplished this with the simple, strong and durable device herein shown.

I claim a-s my invention:

, 1. The combination, with a manger, of a feed hopper supported above the same and having ahingedbottom, latches pivoted ad jacent to said hinged bottom and engaging the same for normally looking it in its closed position, a sliding bar mounted to engage and trip said latches, a hammer for engaging said bar, trip mechanism for moving said'hammer to its actuating position, and a time piece for operating said trip mechanism at a predetermined period.

2. The combination, with a manger, of a feed hopper and a hinged bottom therefor, mechanism for normally locking said bottom in its closed position, a hammer mounted to move said lockingmechanism to its release position, a'lever having a head to normally receive and support said hammer,

atriplever' mounted to engage said hammer-supporting lever and normally lock it in its supporting position, and a time piece having means for engaging and moving said trip lever to its release position.

8. The combination, with a hopper having-a discharge opening and a floor normally closing saidopening, a locking mechanism for said floor, an actuating hammer for said locking mechanism, a lever having a head to. receive said hammer and normally support it, a trip lever for engaging said hammer-supporting lever and holding it in its locking position, and a time piece having a cam mounted to engagesaid trip lever and operate it at a predetermined period.

t. An automatic stock feeder comprising a hopper provided with a discharge opening, and means for normally closing said opening, a mechanism for tripping said closmeans and comprising a tilting hammer and a locking lever therefor, a trip lever engaging said locking lever, a revoluble cam, having a high surface to engage said trip lever and hold it in its locking position, said cam having a stud and a time piece having an alarm post provided with a socket to receive said stud, the revolution of said stud revolving said cam to present its loW 'surface'to said locking lever at a. predeter mined period.
